D8, D8+ and C1 — hoist classifications explained
What the entertainment industry's hoist grades actually require, and when each is mandatory.
How we verify
Every hoist carries one of three labels. The label says where its specifications came from.
- Checked
- We checked the specs against a maker document: a datasheet, manual or catalogue. The page and table are cited in the source notes.
- Maker page
- We took the specs from the maker's own page for this product or its family. Not yet checked against a datasheet.
- Unverified
- A real product line, listed for reference. We removed every spec we could not source. A line seen only on a maker's homepage or category listing stays here.
Checked and Maker page together count as verified. The Ask assistant answers from verified hoists only. Photos follow the same rule: we show a photo only when it comes from the hoist's own page or its family's page.
Where the names come from
The grades originate in the German trade-association rules — BGV D8 (hoists, later DGUV Vorschrift 54) and BGV C1 (staging and production facilities for the entertainment industry, later DGUV Vorschrift 17). Because German rental stock dominates world touring, the shorthand "D8 / D8+ / C1" became the international language for stage hoist duty.
Two newer documents now carry the technical substance:
- IGVW SQP2 (current edition 2024) — the German industry standard of quality that defines the D8 / D8+ / C1 executions in practice. Manufacturers certify against it (e.g. GIS: "in accordance with EN 14492-2 and IGVW SQP2:2024").
- EN 17206:2020 — the European machinery standard for entertainment lifting, which replaces the letter-grades with use cases (UC1–UC6) based on what moves, when, and over whom.

D8 baseline
A standard industrial electric chain hoist (EN 14492-2) prepared for event use — typically climbing on its chain, used without a handheld pendant.
- Loads must NOT hang over people without a secondary safety (safety steel) once the movement is complete.
- Chain safety factor commonly 4–5:1 (GIS LPL D8: min 5:1).
- Single brake acceptable; second brake often optional.
- EN 17206 orientation: UC1–UC2 (MOVEKET D8 ECO: "prepared for EN17206 UC1 – UC2").
Cited: IGVW SQP2; GIS D8 product text ("installation of a secondary safety component is required to fix the load"); MOVEKET series pages.
D8+ hold over people
An uprated D8 that may statically hold loads above people without a secondary — the workhorse grade for touring rigs. Still not for moving loads over people during the show.
- Chain safety factor min 8:1 (GIS LPL D8+; ProLyft NERO 8:1; LIFTKET STAGEKET D8+).
- Two independent brakes, each rated to hold the load (GIS: "two independent DC spring-loaded brakes"; Kinesys Apex: dual fail-safe brakes each full-load rated).
- Capacity is derated vs the same hoist's D8 execution — see the table below.
- EN 17206 orientation: UC1–UC2 static-hold duty (MOVEKET D8 PLUS SAFETY: "prepared for EN17206 UC1 – UC2").
Cited: IGVW SQP2; GIS, MOVEKET, ProLyft, LIFTKET product data in this database.
C1 move over people
The show-machinery grade: moving loads above people during the performance, kinetic scenery, and — with additional conditions — performer flying.
- Chain safety factor min 10:1 (GIS LP C1 / LPL C1).
- Dual independent brakes plus monitored control: load and position monitoring, group emergency stop, safety-rated control chain (Kinesys Apex system reaches SIL3 per EN 62061 only as a system with its Mentor safety controller).
- Control comes from a system interface, not a pendant (GIS C1: "interface for control system provided by the customer").
- EN 17206 orientation: UC3–UC4 (moving loads over people; MOVEKET C1 INSTALLATION: "prepared for EN17206 UC3 – UC4"); performer flying is UC5–UC6 with further requirements.

The clearest proof: one hoist body, three ratings
GIS sells the same LPL body in all three executions. Watch the capacity fall as the safety demands rise — classification is not a sticker, it is a re-rating:
| Model | as D8 (5:1) | as D8+ (8:1) | as C1 (10:1) |
|---|---|---|---|
| GIS LPML250 / LPL500 | 1000 kg | 630 kg | 500 kg |
| GIS LPL1000 | 2000 kg | 1250 kg | 1000 kg |

Quick decision rule
- Load comes in, gets trimmed, nobody underneath afterwards → D8 (+ secondary if anyone could pass below).
- Load hangs above people during doors/show but does not move → D8+.
- Anything moves above people during the show → C1-class system with monitored control.
- A person is on the moving load → EN 17206 UC5/UC6 territory: documented risk assessment and rescue plan by a qualified person are mandatory preconditions, beyond the hoist grade itself.
Item 4 per the Kinesys Apex Hoist manual (people-carrying prohibited except under documented RA + rescue plan by a qualified person).
